RE: I have wondered about that

It's not simply a matter of the station upgrading and the consumer upgrading. There is a reason no one is broadcasting 1080p over the air--it's not practical. Even 1080i and 720p are tough to broadcast without resulting in compression artifacts.

But again, as we've been trying to tell you, interlacing is not an analog technology. It's a way to trick the eye into thinking it's seeing solid frames without having to broadcast solid frames--which reduces the bandwidth required. That's why it was important for analog sets that didn't have the processing power of new HDTV sets, but you're wrong in thinking interlacing is an analog technology per se.
